Exploiting Weak Permissions on OU in Active Directory?

I created an environment, where I allowed a user named demop with these four permissions


on an OU named VulnerableOU? And, I have Meterpreter access to the user’s PC, so how can I exploit this behavior? Or in other words how this can be exploitable in real scenarios?

By these permissions it looks like we can create an object inside an OU but How? What tool should I use or maybe what PowerShell cmdlet should I use?

Dell Inspiron 3538 (with Qualcomm Atheros QCA9377) has weak Wi-Fi signal on Ubuntu 18.04.3 LTS

Yesterday I bought Dell’s Inspiron 3538 with preinstalled Ubuntu 18.04.3 LTS.

Everything works pretty much fine (well, there were minor issues as missing a language, a timezone and a region during setup which normally do not miss with vanilla Ubuntu) except Wi-Fi.

For some reason Wi-Fi signal is blatantly weak. First I went to Additional Drivers, there was a wireless device first time I opened Additional Drivers, now it is missing, Ubuntu is not showing it anymore. So I cannot change driver there.

Then I tried installing backports according to this question. I tried few versions, none of them helped. Kernel I am using is 4.15.0-1057-oem.

I really do not know what to do next except installing another kernel (which one?) or just removing preinstalled Ubuntu, download vanilla Ubuntu and install it.

Which is really bad because I bought this Dell explicitly because of its support for Ubuntu and I expected everything to be smooth.

Slaad Chaos Phage: Weak Combat Ability?

Slaad Chaos Phage seems like an odd ability in 5e. They offer no real disadvantages to the party that forces them to expend resources because they require days to take effect: Red Slaad Tadpoles kill whoever they infect in three months while Blue Slaad plague causes maximum HP reduction per day until the target is turned into a Slaad.

In short, as far as I can see, a Slaad infection doesn’t seem to be increase the fighting proficiency of the Slaads in anyway.

Which then brings up the question of how are they supposed to work towards increasing the difficulty of an encounter, since Slaad infections are diseases, and Lesser Restoration is a fairly low level spell.

  1. A party without access to it is unlikely to survive the Slaad in the first place.
  2. A party that is sufficiently high leveled to take down a Slaad would probably have lesser restoration on hand, which they can cast and then long rest to regain all their spells.

The alternative would be keeping infections a secret and the party suddenly wake up one day with a member-turned-Slaad trying to eat their face off. This though seems to be a power move with no counter and extremely unfair for the party, especially for Blue Slaad phage since it means one character is automatically removed from play with no hope of reversal unless someone has Wish handy. At least someone killed by a Tadpole can still be revivified.

Wouldn’t a Slaad infection that causes creatures to turn before the day ends or even mid encounter (A la XCOM Chryssalids) be a more sensible flavor ability? This infection would force players to expend potions/spells slots in the encounter and serves a point to effectively deplete player resources.

Wifi weak and slow

I’ve bought a new laptop. I’ve installed ubuntu 18.04.3 . All went well except wifi signal, it’s weak and slow. I’ve tried several commands on terminal for knowing which wifi adapter it has, but only could see it uses a generic driver. What can I do? Thanks a lot.

Weak Wifi Signal on Ubuntu

Before I tell you the story, note that I search all topics and do most of tips but I have still this problem and nothing changed.

I have very weak WiFi signal on Ubuntu . below there are some information about my system. please help me to reach WWW via WiFi on Ubuntu. thanks

Is 7-zip encryption “weak”?

I can across this which implies (to me) that 7-zip AES implementation is not good:


Can some knowledgeable person or expect please comment and clarify? Thanks.

Weak convergence for generic periodic points that obtains from specification

Let $ X$ be a compact metric space and let $ f:X\rightarrow X$ be a Anosov and transitive map.

Let $ x$ be a generic point so that $ $ \mu_{n_{i}}:=\frac{1}{n_{i}}\sum_{j=0}^{n_{i}-1} \delta_{T^{j}(x)} \rightarrow \mu $ $ for some invariant measure $ \mu$ .

It is well known that $ T$ satisfies the specification property. Let $ p\in X$ be a periodic point associated to $ \delta, S$ and $ \{ x, f(x), . . . , f^{n_{i}}(x)\}$ by the specification property. In particular, $ f^{n_{i}+S}(p) = p$ and orbit of $ p$ cover orbit of $ f^{n_{i}}(x)$ .

My first question is as follows:

$ \mu_{n_{i},p}:=\frac{1}{n_{i}+S}\sum_{j=0}^{n_{i}+S-1} \delta_{T^{i}(p)} \rightarrow \mu $ ?

If yes. For $ \mu\in\mathcal M(X)$ we write $ \text{supp} \mu$ for the support of $ \mu$ . It is easy to see that if a sequence of measures $ (\mu_n)_{n=1}^\infty$ weak$ ^*$ converges to some $ \mu\in\mathcal M(X)$ , then $ $ \text{supp}\, \mu\subset \liminf_{n\to\infty}(\text{supp}\,\mu_n). $ $ (By $ \liminf$ above I mean the Kuratowski limit inferior, for a definition see wikipedia entry.)

According to above, Can we say $ supp \mu$ is periodic point? Because $ \mu_{n_{i},p}$ has periodic support.

Computing weak operadic colimits as colimits

I am trying to reduce the computation of weak operadic colimits to colimits. Let me introduct some notation. Let $ q:C^{\otimes} \to N(Fin_*)$ be a

Let $ p: K \to C^{\otimes}_{act}$ be a diagram. Define $ p^{\otimes}: K \to C$ in the following way. For every $ k \in K$ , there is a cocartesian lifting $ s(k): p(k) \to k’$ of the unique active map $ qp(k) \to <1>$ .

Furthermore, we have an homotopy between $ qp: K \to N(Fin_*)^{act}$ and the constant functor $ <1>$ , because $ <1>$ is final in $ N(Fin_*)^{act}$ .

By a lemma used in the proof of the existence of transition functors, one can lift this homotopy to an homotopy $ H: K \times \Delta^1 \to C^{\otimes}_{act}$ . In particular, this yield a functor $ p^{\otimes}: K \to C$ , the underlying category of $ C^{\otimes}$ .

Set $ C^{act}_{p/}:= C \times_{C^{\otimes}_{act}} (C^{\otimes}_{act})_{p/} $ , i.e. cocones with cocone point lying over 1. I want to show that $ $ C^{act}_{p/} \simeq C_{p^{\otimes}/} $ $

The idea behind is the following: if $ K$ was a point, we could lift a map $ p^{\otimes}(k) \to c$ to a map $ p(k) \to c$ via the cocartesian lift $ s(k)$ . This realizes the intuitive idea that $ Mul_{C^{\otimes}}( (X_1, \ldots, X_n), c) \simeq Hom_C( X_1 \otimes \ldots \otimes X_n, c)$ . I believe that this could be generalized to arbitrary diagrams: intuitively, if we have a cone towards an object lying over 1, this factors through a cone lying over 1, made of “pointwise tensor products”.

Note that this would yield the following

Corollary. Let $ \bar{p}:K^{\triangleright} \to C^{\otimes}_{act}$ a diagram. Then it is a weak operadic q-colimit diagram iff $ \bar{p}^{\otimes}$ is a colimit diagram, because equivalences preserve initial objects.

I would be happy also if someone could solve the case $ K=\Delta^1$ , that would shed light on how to solve the general case simplex by simplex.

Weak enrichment and bicategories

I’m trying to find examples where the following perspective on bicategories is developed.

We can define a 2-category as being enriched in Cat, where Cat is treated as a monoidal category using the Cartesian product. It seems like you can treat a bicategory as a weak enrichment, where the necessary associativity diagrams are weakened and replaced with the associator and unitor 2-cells.

This seems to make certain things much simpler, particularly if you wanted to work with a bicategory whose hom-categories were categories with structure and the composition and coherent 2-cells were to respect that structure. That also makes me think that something goes wrong when you take this approach, because I can’t seem to find any references where this is developed.
